One-time forming processing device of square pipe hoop

Abstract

The invention discloses a one-time forming processing device of a square pipe hoop. The one-time forming processing device comprises a mold frame mechanism and a linkage extrusion mechanism, wherein the mold frame mechanism comprises a mold frame upper bottom plate, a guide sleeve, a guide column, a guide column fixing seat and a mold frame lower bottom plate; and the linkage extrusion mechanism comprises an upper punch, an upper fixing plate, a middle upper plate, an upper elastic body, a sliding block, a clamping block, a middle lower plate, a lower punch, a lower fixing plate and a lower elastic body. According to the one-time forming processing device of the square pipe hoop, one-time clamping and positioning are adopted in the production process, the positioning consistency is good, and the requirement for the shape and position tolerance of hoop bodies and a square through hole is fundamentally met; and the heights of the hoop bodies at the two ends and the symmetry of the hoop bodies are high, the hoop bodies are regular, the surface roughness is low, no crack distortion defect is caused, the consistency of the hoop bodies of the square pipe hoop is high, and the quality ofiron art subsequent assembly is ensured.

Description

technical field [0001] The invention relates to the technical field of forming and processing of metal profiles, in particular to a one-time forming and processing device for square tube hoops. Background technique [0002] Square tube hoop is a decorative product of wrought iron. It is required to be natural and beautiful after forming, and to attract customers with its beautiful shape. The shape of the square tube hoop is as attached Figure 1-2 As shown, it includes a square tube hoop body 100, a square through hole 103 is arranged in the square tube hoop body 100, and two protruding hoop bodies 102 are respectively provided at both ends of the side wall 101 of the square tube hoop body 100. The original square tube hoop manufacturing process is to first press the protruding hoop body 102 at one end of the square tube hoop body 100, and then press the other end of the square tube hoop body 100 into the protruding hoop body 102. This manufacturing process has the followin...

Problems solved by technology

The original square tube hoop manufacturing process is to first press the protruding hoop body 102 at one end of the square tube hoop body 100, and then press the other end of the square tube hoop body 100 into the protruding hoop body 102. This manufacturing process has the following main disadvantages: 1. Secondary clamping is required in the production process, wherein the positioning of the second clamping is inaccurate, the consistency of the positioning of the secondary clamping is poor, and the shape and position tolerances of the hoop body 102 and the square through hole 103 are difficult. 2. The height of the hoop body 102 at both ends and the symmetry of the hoop body 102 are poor; 3. The hoop body 102 is prone to irregular distortion and even surface cracks relative to the square through hole 103; Body 102 has high surface roughness and many surface scratches; 5. There are many processes, high production cost, and low economic efficiency; 6. After assembly with other wrought iron workpieces, the overall consistency is poor, which affects the overall aesthetics of wrought iron; 7. The product is in The backwardness in technology, economy and quality leads to weak market competitiveness
